My computer isn't fantastic for gaming, but it's pretty decent. Specifically I have an APU, an A6-3600 with an AMD Radeon HD 6530D GPU. I'm a noob to PC gaming and don't know much about proper ways to upgrade but I'm pretty sure I can't just stick the highest end graphics card out there and expect everything to be great. I would like to improve my performance in games at the 1600x900 resolution I play at and I frequently play more demanding games in a 1280x720 window just to get a playable performance. I'd love to just get a completely powerful new gaming PC but don't have the money for that so working with I have will have to do.
So if any more tech savvy people can give me suggestions on how to go about this I'd appreciate it.
Specifically this is the exact computer I have http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03072349&lang=en&cc=us&taskId=101&contentType=SupportFAQ&prodSeriesId=5151865&prodTypeId=12454
